With tickets selling out fast, Riot Fest is one of Chicago's most anticipated music festivals of the summer thanks to a wild lineup including headliners Fall Out Boy, Blink 182, Violent Femmes, Blondie, AFI, Public Enemy and an as-yet-unidentified secret headliner.

We wanted to make sure our faithful readers had an extra shot at making it to the Sept. 13-15 festival (and carnival!) at the city's Humboldt Park, so we've partnered with Riot Fest to offer up a pair of three-day general admission passes to the event.

UPDATE: The giveaway has ended and a winner has been selected and notified. Be sure to follow HuffPost Chicago on Twitterand Facebook for more ticket giveaways to Riot Fest and other Chicagoland events throughout the summer.
